Mark, I assume 'backup-skip' metadata key did not exist before metadata_get call? Otherwise I would not expect the error.
Anyway, there is a bug in the metadata function error handling I fix in this PR: https://github.com/ceph/ceph/pull/19337
Note, with the fix it will still throw the exception in the case like yours, though the error will be different:
"ImageNotFound: [errno 2] error getting metadata backup-skip for image ...". You will need to catch the exception if you want to tolerate non-existent keys.
